The Lowdown

Alright, let's get into it. The surf window kicks off Wednesday the 9th with some clean conditions at Jaconé. It’s a bit of a building story, so let's walk through it.

Wednesday morning is looking pretty special. We’ve got a 6ft ENE swell pushing through with a 7-second period, and the wind is dead glassy out of the N. The water’s about average for this time of year, so no surprises there. This is the kind of session you paddle out for - clean, lined-up, and the cove will be handling it. The energy reading is at 648, which is moderate, but the conditions are the story here. The afternoon goes downhill though, as the wind swings S and brings light rain with it. It won’t be the same wave.

Thursday the 10th sees the swell drop to 4ft, but it’s switching to a S direction with a solid 12-second period. The morning is a bit messy with a cross-shore NW wind, but by the afternoon, the wind goes offshore from the NNE. It’ll be clean and rideable, just not as much push. Think of it as a fun, grovelly day.

Friday the 11th is where things start to get interesting. The swell is still 4ft from the S, but the period jumps to 14 seconds. That’s a proper groundswell, and it’ll have some real punch. The morning is offshore NE wind, and it’s clean. The afternoon gets even better with a cross-offshore ESE breeze. The energy is moving up to 827, and this is a standout morning. The wave will be holding its shape nicely. Keep this one in mind.

Saturday the 12th is a washout. Strong WSW winds, rain, and the swell drops to under 3ft. It’s not worth your time, and the energy drops way down to 239. Forget it.

Sunday the 13th brings the biggest swell of the period. We’re looking at 8ft from the S with an 11-second period in the afternoon, and the energy is cranking at 1299. This is a powerful, strong swell. Since it’s over 8ft, it’s expert territory. The morning is still a bit lumpy with a cross-shore SE wind, but the afternoon cleans up nicely with a cross-offshore ESE breeze. This is the standout of the whole window for experienced surfers. The paddle out will be work, but the sets will be worth it. This is big, powerful surf.

Monday the 14th drops back down, but it's still fun. The morning is clean with a cross-offshore ENE wind and 6ft of swell. The afternoon the wind goes full offshore from the ENE, and it gets even better. A solid day.

Tuesday the 15th has a bit of swell left, but the afternoon turns onshore from the SSW. The morning is the go-to with a gentle offshore NNE wind. It’s smaller, around 3ft, but clean.

Wednesday the 16th is onshore and messy, with the swell around 5ft but the wind will make it a choppy mess.

Now, looking further out into the second week, the big one is Thursday the 17th. The swell jumps dramatically, hitting 6ft from the S with a massive 16-second period. The energy reading is off the charts at 2360 – that’s very strong. The morning is glassy with a light offshore ENE wind. This is a serious groundswell, and it’s going to be breaking fast and hollow. The period is really long, so at a beach break like this, it might be a bit straight, but it will have so much power. It’s another expert session, but it’s a promising one. The afternoon backs off a touch.

Friday the 18th is still good in the morning with a 6ft S swell and 13-second period, and offshore NNE wind. The afternoon goes to crap with onshore WSW wind.

Saturday the 19th is fun and clean for most of the day, with light winds and glassy conditions in the afternoon. Swell is around 3ft.

Sunday the 20th is small but glassy in the morning. It’s a longboarder’s day, not a performance wave.

Monday and Tuesday of the next week are small and clean. The swell drops off, and it’s pretty average.

Wednesday the 23rd is glassy with no wind, and Thursday the 24th is also glassy in the morning. It’s flat and small, not much to write home about.

So, to sum it up: the first standout is Sunday the 13th afternoon – big, powerful, clean, expert-only. The second is Thursday the 17th morning – massive, long-period groundswell, glassy, and very strong. Those are your two best bets. Everything else is just keeping you wet.

Remember, the long-range stuff is promising but could still shift. Get out there when you can.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
